How to self test for leakage of hidden water pipes? How to detect where the water leaks in the burie

First of all, turn off the main switch of the water pipe, turn on the faucet in the room until the faucet is empty, and turn off the water inlet switch of the toilet tank and washing machine and other equipment with water storage function. Turn on the main switch of the water pipe, 20 minutes after opening to see if the water meter is moving, including slow walking, if there is walking, it is leaking, if there is no movement, it may be fine.

1) Close the main valve of the water pipe. (i.e. the water pipe switch in front of the water meter) 2) Turn on the faucet in the room for 20 minutes, make sure there is no more water dripping and turn off all the faucets.

3) Turn off the water inlet switch of equipment with water storage function, such as toilet tanks and washing machines.

4) Open the main valve of the water pipe.

Check the meter for movement, including slow movement, 20 minutes after opening the main valve. If there is movement, it is a water leak. If you don't move around, you'll probably be fine.

If there is a problem with the water meter or if the water pipe is slightly percolated, it may be difficult to determine. Therefore, it is recommended that the water pressure test experiment must be carried out after the construction, generally 8 kg, and the time is 20-30 minutes. (It's best to see it in person).

Water pipe direction: It is recommended that the water pipe go to the top is the safest. The main reason is that most of the waterway reconstruction is done by dark pipes, and the characteristic of water is that water flows to a lower place.

If the pipeline goes underground, it is difficult to find the leakage in time once it occurs, and the leakage will only be found if the water overflows or the floor is deformed and leaks downstairs, and it is difficult to find the leakage because the water pipe is buried in the dark. At this time, the huge loss is irreparable, and even seriously affects the friendly neighborly relationship; If the water pipes go to the top, it may be more expensive to change the water, but as a long-term investment, it is worth it. Even if the water pipe goes to the top, even if the water leaks, it can be found in time, which is convenient for maintenance and the loss is small.

In daily life, if you find any of the following, please check the relevant pipes as soon as possible

Water pipes go underground:

1) The surface of the wall paint is moldy and blistered.

2) Blackening of baseboards or wooden floors and fine bubbles on the surface.

Water pipe goes to the top:

1) Dampness or water dripping on the canopy.

2) There is dampness or water seepage out of the wall tiles of the pipe.

The detection is as follows:

1. If it is a water pipe exposed to the outside and there is a water leakage, the detection method is very simple, you can wipe the surface of the water pipe clean, and then observe it to see which piece will be watery and which area is wet, which means that the water leakage point is in.

2. If the water pipe buried in the wall or in the ground is leaking, you can use a professional water leakage detector to detect, this instrument is mainly judged by sound, so the results of the detection are more accurate, after all, when the water leaks out, it will make noise.

3. You can do the pressure test, so that you can do one by one investigation, in the process of suppression, if the pressure value drops very seriously, it means that there is a water leakage problem in this water pipe, if the pressure value is normal, there is no water leakage.

Water leak repair

First, use a small hacksaw to see off the leakage, and the saw edge must be flat. Use sandpaper to gently sand the newly exposed port, but not too much. Then wipe the port clean with a clean cloth, apply the special glue to the port, let it dry for a while, and apply the glue in the "bamboo" joint at this time.

Finally, connect the port to the "bamboo" and turn it repeatedly until it is firm. The same way to connect the other end. Wait until all this is done before applying an appropriate amount of glue to the joints to ensure that the water pipe does not leak.

Introduction to the method of concealed pipe leakage detection and maintenance:

1. The professional master of Qing uses professional instruments to detect, and then repairs the leaking pipeline after accurate positioning.

2. When the dark water pipe at home leaks, the main valve of the water pipe at home should be closed first. The main valve of the water pipe refers to the water pipe switch in front of the water meter. Then turn on all the faucets in the room for about 20 minutes, and then turn off all the faucets that are turned on after making sure that there is no water dripping out of the pipes.

Turn off the sluices and drain all areas where there may be water. Find a water pipe to flush the floor drain and hold on for a little longer to see if there will be water leaks downstairs. (Note: Do not let any water flow outside the floor drain at this time, so that you can accurately test whether there is a leaking drain problem).

Caused by the damage of the toilet sewer pipe, the water seepage is not very serious, you can pry open the floor tiles near the floor drain and dig out a space nearly 3cm deep, and then use the plugging king to plug it, and carry out a closed water test experiment for about 1 hour to check whether there is still water seepage. If the water seeps continues, you need to ask a professional worker to replace the cast iron sewer pipe, and it is best to replace all the sewer pipes made of PVC or PE material.

Precautions in case of leaking water pipes

When we check the cause of a water leak, we should first turn off all the power supplies, which is an important step. So before checking the cause of the water leak, check if the power is turned off, because water conducts electricity and is prone to danger. Then quickly wrap a soft object such as a rag around the leaking area to prevent the water from splashing around.

Checking for a leak in a dark pipe requires the following steps:

1.Turn off all water sources: Turn off all water sources in the room, including faucets, toilets, showers, etc., to ensure that all water sources are turned off.

2.Observe the water meter: Observe the water meter, if the water meter pointer does not move, it means that there is no water flowing, if the pointer is moving, it means that there is water flowing, and further inspection is required.

3.Check the water meter valve next to the water meter: close the water meter valve next to the water meter, if the water meter pointer stops running, it means that after the water meter valve is closed, the water source has been closed, if the pointer is still running, it means that there is a water leakage.

4.Check the dark pipe: check whether the dark pipe is leaking, you can touch the surface of the dark pipe with your hands, if you feel wet or there are water droplets, it means that the dark pipe has water leakage.

5.Check the wall: check whether there is water seepage on the wall, if there are water stains or discoloration on the wall, it means that there is water leakage in the dark pipe.

6.Check the ground: check whether there is water seepage on the ground, if there are water stains or discoloration on the ground, it means that there is water leakage in the dark pipe.

If the cause of the water leak cannot be determined after the above steps, it is recommended to ask a professional plumber to inspect and repair it.

Hidden pipes are pipes that are located in floors or walls, so leaks are often difficult to detect and deal with. Failure to properly check and deal with leaking pipes can cause serious damage to your home. Therefore, Xianhui will introduce the following article to you the method of checking for leakage of hidden pipes.

First of all, you can identify whether there is a leak in the hidden pipe by observing the brother search answer. You can pay attention to whether there are traces of water seepage on the walls of the room, whether there are water stains of water seepage, and whether there is any dampness in the room caused by continuous running water. Especially in places with dense water sources such as bathrooms and kitchens, it is more necessary to pay attention to the possibility of leakage of hidden pipes.

In addition to this, the water test method can also be used to check for leakage in the hidden pipe. The method is to turn off the faucet in the room, then open the valve of the concealed pipe outlet, put a water-resistant small mouth bottle or cup under the concealed pipe outlet, and pay attention to observe whether there will be water droplets or water vapor emitted, if there is, it indicates that the concealed pipe is more likely to leak.

Alternatively, the water meter method can also be used. The specific operation is to turn off all the faucets of the dark pipe and record the initial reading of the water meter. Then close all concealed outlet valves and record the meter readings.

After 12 hours, take the meter reading again, if the reading changes significantly, it indicates that there may be a leak in the hidden pipe.

Finally, if the above methods cannot find the water leakage problem, you need to consider asking a professional plumbing maintenance personnel to check and deal with it. They can detect and deal with hidden pipe leaks with specialized equipment and technology, so as to avoid damage to the house and safety hazards caused by untimely treatment.

In short, through observation, water test method and water meter method, we can preliminarily judge whether the hidden pipe has water leakage. In daily life, we should always check whether there is water leakage in the hidden pipes in the bathroom, kitchen and other places with dense water sources, so as to maintain the safety and health of the house.

Here's how to check for leakage in the dark pipe:

1.Close the main pipe: Close the main pipe of the house first to ensure that the water does not continue to flow during the inspection.

2.Observe the water meter: After the main pipe is closed, observe if there is a change in the reading of the water meter, if the reading continues to increase, there may be a leak in the hidden pipe.

3.Check bathrooms, kitchens and other facilities: Check whether there are traces of water around bathrooms, kitchens and other facilities, if there are traces of water around, there may be leakage in the hidden pipe.

4.Inspect walls and ceilings: Inspect walls and ceilings for signs of water stains, cracks, or discoloration, as they may indicate a leak in a hidden pipe.

5.Check the ground: Sun Na checks the ground for water seepage, deformation, blistering or discoloration, if there are these phenomena, there may be a leakage of hidden pipes.

6.Use tools: Use tools such as stethoscopes or water meters to detect the location and size of leaks in dark pipes.

It should be noted that if the problem of hidden pipe leakage is more serious, it is recommended to seek a professional water pipe repair company to deal with it to avoid greater losses.

Leakage of dark pipes is a latent problem that needs to be discovered and repaired in time. Here are some suggestions to check for leaks in dark pipes:

1.Look for signs of water seepage: First, look for moisture, water seepage, or water stains on your walls, floors, or ceilings. Pay attention to the location, velocity, color, etc. of water seepage so that you can find out possible leaks.

2.Listen for sounds: If there are hidden pipes on walls, floors, or ceilings, you may hear dripping water from water leaks. Try to listen near the area where the water is likely to leak and see if you can hear the dripping sound.

3.Closed Water Test: Close the main valve of the water pipe associated with the leaky area, and then perform a closed water test in the possible leaky area. Pour water over the area where there is a possible leak and observe for leaks. This method may require the assistance of a professional plumber.

4.Check the water pressure: During the closed water test, observe the change in water pressure. If the water pressure drops significantly, it may be a sign of a leaking dark pipe.

5.Check the drains: If the possible leaking area is close to the drain, check the drain for leaks. This can be done by conducting a closed water test near the drain or by observing changes in the amount of water that the drain carries for the rest of the world.

6.Check the floor drain: Check the drain drain rate, and whether there is any abnormal odor. A floor drain can be a hidden location for a hidden pipe leak.

7.Consult a professional: If the cause of the water leak cannot be determined, it is recommended to consult a professional plumber for inspection and repair. They have the expertise and tools to accurately locate and fix hidden pipe leaks.

Please note that when checking for leaks in concealed pipes, it is important to follow the relevant safety procedures. If necessary, contact a professional plumber to do so. Timely detection and repair of concealed pipe leaks can help avoid long-term water damage and repair costs.

1.Observe the water meter: If the water meter is rotating, but no water is being used in the home, it may be a leaking pipe.

2.Observe the water meter pointer: If the front pointer of the water meter keeps turning, even if the water is not being used in the home, it may be a leaking pipe.

3.Observe the meter readings: If the meter readings are increasing but there is no messy use of water at home, it may be a leaking pipe.

4.Listen for the sound of water: If you hear the sound of water inside the wall, it may be a leak in a hidden pipe.

5.Observe the wall: If there is water stains or discoloration on the wall, it may be a leak in the dark pipe.

6.Smell: If you smell musty or damp, it may be a leak in a dark pipe.

7.Observe the water meter box: If there is water in the water meter box, it may be a leaking hidden pipe.

8.Observe the area around the water meter box: If there is standing water around the water meter box, it may be a leaking pipe.

If none of the above methods can determine the leakage of the hidden pipe, it is recommended to ask a professional plumber to inspect and repair it.

Concealed pipe leakage is a relatively hidden water leakage and needs to be checked by the following methods:

1.Observe the wall: If the hidden pipe leaks, there may be water stains, mold, blistering and other phenomena on the wall, and you can judge whether there is water leakage by observing the wall.

2.Listen to the sound: You can tell if the dark pipe is leaking by listening to the sound. You can tap or tap on the wall, and if you hear a hollow sound, it may be caused by a leaking pipe.

3.Use a water leak detector: A water leak detector is a professional tool for detecting water leaks and can be used to detect leaks in hidden pipes. The water leak detector can detect the moisture content of the sensitive collapse inside the wall to determine if there is a water leak.

4.Use an infrared thermal imager: An infrared thermal imager can be used to detect water leaks in hidden pipes. The wall can be scanned with an infrared thermal imager, and if the local temperature of the wall is found to be abnormal, it may be caused by a leak in the dark pipe.

It should be noted that checking for leakage of hidden pipes requires professionals to operate, and it is not recommended to operate by yourself, so as not to build bridges and call circles into greater losses. If you find that the hidden pipe is leaking, it is recommended to contact a professional maintenance chain inspector in time to deal with it.
